This is definitely not a small problem.

 

First off, your class does way, way too much. It seems you're using it as a god object where you put absolutely every feature you need in your application. That's not how OOP works. One class is supposed to have one specific purpose. So the first step is to separate your monster class into multiple simple classes.

 

Then your error handling is fudged up. Instead of simply leaving the PDO exceptions alone so that PHP can log them and stop the script, you catch the exceptions, log only the message (what about the file, line number, stack strace?) and then continue the script. This obviously makes no sense. If you continue with a failed database connection, you'll get nothing but nonsense -- like your non-object error.

 

There are other problems, but let's start with those two.
